Abstract
An evaporative humidifier includes a top cover and a water reservoir tank removably mounted on top of a base platform. Several of the components of the humidifier contain a biocide for resisting the growth of bacteria and fungi on all surfaces of the components. The humidifier includes, in one embodiment, a pump assembly for moving water from the base platform to the top of an evaporator panel disposed in an air stream drawn through the humidifier. Alternatively, a paper wick is partially submerged in the pool of water in the base platform for drawing water up into the air stream by capillary action.
Claims47
An evaporative humidifier comprising:
- a base platform, said base platform being formed from a material which contains a first biocide for resisting growth of bacteria and fungi on said base platform,
- a top cover removably mounted on said base platform,
- a water reservoir tank removably mounted on said base platform for releasing water into said base platform to a predetermined depth,
- an evaporator panel assembly for holding water received from said base platform, said evaporator panel assembly including a frame mounted on said base platform and an evaporator panel disposed within said frame,
- a fan assembly for drawing air into the humidifier across said evaporator panel assembly and for forcing air out of the humidifier.
2 more elements
An evaporative humidifier comprising:
- a housing having an air stream drawn in through an air inlet and passed out of an air outlet,
- a supply of water to said housing for retention as a pool of water,
- a water retaining element for placing water in said air stream, said water retaining element being located intermediate of said air inlet and said air outlet,
- a base platform of said housing for retaining said pool of water,
- said base platform being made of a material containing a biocide for resisting growth of bacteria and fungi on said base platform.
2 more elements
An evaporative humidifier comprising:
- a base platform,
- a top cover removably mounted on said base platform,
